SPARK ARRESTED. AND SMOIIE'ELIMINATOR.

Application filed September 29, 1922. Serial No. 591,218.

My invention consists of a novel construction of a spark arrester andsmoke elimlnator, which is adapted to be readily attached to cupolastacks and smoke stacks or the like, of any character,'whereby I am en-'abled, by the install n of device to eliminate sparks, oxides nd carbonfrom the fumes emitted from said stack, said fumes beingcaused by mynovel apparatus to pass through a curtain orwall of water of such acharacter that sparks, oxides, carbon and the like will be entrappedwithin the arrester whereby the waste gases which finally emerge from mynovel apparatus are purified of certain deleterious elements orimpurities.

T o the above ends my invention consists of a novel construction of acasing having an upper outlet for the'purified gases below which Ilocate means for creating the curtain or wall of water which is receivedin a suitable lower receptacle provided with a drain pipe, and anoverflow, so that the apparatus is at all times automatic in itsoperation after having once been installed in position with respect tothe stack.

It further consists of other novel features as will be hereinaftervention, I have shown in the accompanying drawing a form thereof whichisat present preferred by me, since it will give in practicesatisfactory and reliable results, although it is to be understood thatthe various instrumentalities of which. my invention consists can "bevariously arranged and organized and that my invention is not limited tothe precise arrangement and organization of these instrumentalities asherein shown and described. a

Refe 'ringto the drawings.

In carrying out my invention which is adapted to be applied to the upperportion of a cupola stack or smoke stack as 1, I

employ an outer casing 2, which is prefer ably circular or annular incontour and which is provided at its lower portion with a base member 3,the inner portion of said base member fitting nicely around the upperportion of the smoke stack 1, and being supported with respect theretoby any suitable inleans, as angle irons or brackets 4:, or the ire.

The annular casing member 2 may be prolonged downwardly to form thelower conical member'fi, whose lower end as indicated at 6 contacts withand/incloses the stack 1, so as to-give the upper portion of the lattera neat and finished appearance, when my invention is installed thereon.

The base member 3 is provided with a- 1O deslgnates an inner annularvertical wall, which is supported upon the base member 3 and securedwith respect thereto by the outer annular l.-iron orangle iron 11 andthe inner annular L-iron or angle iron 12, the lower edge of said wall10 being riveted or otherwise securedto said angle irons.

- The junction of the outer edge of the base member 3 with the lowerinner surface of the vertical outer wall 2 is also provided with anannular L-iron or angle iron 13 and I preferably caulk the, upper-edgesof the annular angle.irons 11 and 13, so that an annular water tightchamber, which I have-designated as 14 is formed between the outer.upright wall 2, the horizontal base member or wall 3 and the inner wall10.

For the purpose of. reinforcing the upper edge of the inner wall 10, Iprovide the latter with the annular angle iron 15 which may be rivetedor otherwise secured thereto,

and to the inner'surface of the wall 10, I secure theilower ends of thearms-16, which have the upper inwardly deflected terminals i 17, uponwhich the conical shaped roof or 'bafile 18 is supported.

19 designates uprights having the. feet 20, which are secured to theroof 18 and the upper terminals 21, upon which is supported theperforated plate or conical or dished :tive overflow will be providedtherefor.

water distributing device, which is providedv water baflie having thecentral opening 27 which; is secured to the upper end of the outercasing 2 preferably by means of the outer annular, angular ring 28,which is riveted or othewise secured to the upper outer end of thecasing 2, The interior surface of the annular casing 2 is reinforced atvarious intervals by means of the angular uprights 28, which are spacedapart as seen in Figure 2, and it will be evident that a very strong,rigid and durable structure is provided which can be cheaplymanufactured and assembled by using standard rolled metal shapes.

29 designates a manhole opening in the bottom member or wall 3 abovewhich is the cover 30 which is secured in any suitthe her, it will beunderstood that the fumes,

gases, oxides, carbon and the like will be ssuing through the-stack 1.

Water having been admitted throughthe pipe 24, will fall upon theperforated plate 22 and will flow through the perforations and over theouter peripheral edge thereof onto member 18. A film is formed by thewater drippin from the edge of member 18, through w 'ch film the fumesissuing from the stack 1 must pass, it being apparent that the outerperipheral edge of the roof member 18 overhangs both the top of thestack 1 and the outer edge of the annular angle iron or flange 15. n

The sparks, oxides, carbon and other products of combustion will firstimpinge on the bottom of the baflie 18 and then be deflected laterallytowards and through the liquid curtain, and will be arrested by saidvertical curtain or wall of water and then precipitated into the annularchamber 14 land will automatically flowtherefrom through point. a

In case the water level within the annular the port 7 and pipe 8 to anydesired chamber 14 should arise to the height in- I 'dicated by the port9, seen at the right of Figure 1, it will be apparent that an eflec- Vments may be assembled in other ways The purified fumes, gases and thelikef after passing through the curtain of water flowing over theperipheral edge of the member 18, pass to the atmosphere throughthefinalcentral exit opening 27, the deleterious impurities beingtrapped in the annular chamber 14. l

Upon the removal of the manhole cover 30, access can be readilychad tothe chamber 14, asis evident.

It will consequently be seen from the foregoing construction that I haveprovided a novel and effective means, whereby sparks, oxides, carbonsand the like ,Will be entrapped and eliminated from the fumes emittedfrom the stack to which my invention is applied.

In the construction seen in Figure 3, I have shown a device wherein theroof member 18 and its supports 16 conform to the structure seen inFigure 1,; as well as they uprights 10 supported upon the roof member18.

lnvlieu of the perforated conical or dishshaped roof 22, seen in Figure1, I may employ the conical solid member 32 against the bottom of whichthe incoming water is discharged through the outlet 33 which isattachedto the water supply pipe '34.

It will be apparent that the principle of my invention is the same inboth cases, since the water impinging on the member 18 will flowtherefrom in the shape of an umbrella e curtain or wall in bothconstructions, seen in Figures 1 and 3 andwill efl'ectively charged fromthe stack 1 and impinge upon the bottom of the roof member 18.

shown the outer casing 2 as'having a circular or annular contour, thesame may have any other desired contour without depart- 7 ing from thespirit of my invention, and

while I have shown the preferred manner of assembling the bottom member3 and the upright walls 2 and 10 and the-roof member 18, so that astructure "possessing the requi site rigidity and durablility may beproduced, it will be apparent that these elewithout departing from thespirit of my invention.

It will be apparent that the baflle 18 in boththe'constructions seen inFigures 1 and 3 Serve to deflect laterally the fumes issuing fromthestack and that said bafile is keptcool in the construction seen inFigure 1 by .the water dropped thereon through the ports 23 and in theconstruction seen in Figure the baflle 18 is he t cool by'the waterfalling purify the fumes or gases which are dis- 1 thereon. In botheconstructions seen in through in the statement of the invention and the.above description, and while I have in the present instance, shown anddescribed a'preferred embodiment thereofwhich will give in practice.satisfactory 'and' reliable results,

it Is to be understood that such embodiment ,is susceptible ofmodification in ,various particulars without departing M from the spiritor scope of the invention or sacrificing 1 an of its advantages.'

aving thus described my invention what I claim as.' new and desire "tosecure by:
